Be it known that l, RICHARD E. COLE, a citizen of the United States ofAmerica, residing at Columbus, in the county of Franklin and State ofOhio, have invented certain new and useful Improvements in. Containers,of which the following is specilication.

Mypresent invention relates generally to containers of that naturedesigned to protect the contents thereof from external influence. andresides more particularly in a container for preserving photographicfilms, plates and the like as well as blue print papers and othermaterials detrimentally affected by the ordinary atmosphere andespecially damp air.

The primary object of my invention is the provision of a container ofthis nature which will be capable of more or less rough handling in useas Well as transportation and which provides for ready introduction orremoval of the material to be stored or shipped.

A further object is the pro-vision of a container having means wherebyto defeat ill effects of carelessness in failing to replace the lid, anda stil] further object is the provision of a comparatively simpleinexpensive and durable container in connection With which the airdrying chemicals or compounds may be readily renewed from time to time,and conveniently held therein.

In the accompanying drawing, Which illustrates my invention and forms apartof the specification,

Figure lis a front elevation.

Figure 2 is a central vertical section.

Figure 3 is an enlarged vertical section talren on line 3-3 of Figure 1,and

Figures 4 and 5 are enlarged horizontal sections taken respectively onlines 4-4 and 5-5 of Figure 2.

Referring now to these figures, the body 10 of my improved container ispreferably of vertical cylindrical form with a doubled internal annularrib 11 adjacent to its edge on which rib a base plate 12 is seated. Thisrib 11 thus not only reinforces the lower edge of the container body,but also receives thereon and supports the base plate, Whose peripheraledge snugly interfits the cylindrical body 10.

The lovver portion of the body has an outer reinforcing wall 13surrounding the saine in close contact therewith and provided at pointsabove the base plate 12, with yvertically spaced outer annular ribs 15which serve to further reinforce and strengthen the lower portion of thebody 10.

A false bottom 16 is preferably formed. of heavy mesh screening materialsecured at its periphery to a ring 17 the latter of which has atcircumferential l,spaced points depending legs 18 Whose lower angularends 19 rest on the base plate 12, ln reality hovvever this false bottomforms the base of the chamber Within body 10 Which chamber abovethereticulate base receives the films, plates, blue print papers, etc.to be preserved against deterioration, and vits nature is such as toplace this material receiving chamber in open communication With thecompartment of the body existing between the false bottom 16 and thebase plate 12. This last mentioned compartment receives chemical holdingbags 2O preferably in the shape shown in Figures 2 and 5 so that theymay be separately introduced through the upper end when the reticulatebase has been removed.

Each of the bags 2O in practice contains a dry powdered or granularchemical or other suitable material for absorbing moisture out of theair within the container, Inaterial in the form stated being preferredalthough it may be of liquid form except in case of shipment.

The upper edge of the body 10 is preferably tlanged for added strengthand also has vertically spaced inner annular ribs 21 belowsaid edge, theupper rib 21 forming a supporting ring for the inner closure plate 22 ofthe material receiving chamber. This plate. is of less diameter than thebody 10, and has an upper handle 23, and a depending apertured lug 24,the latter receiving the upper end of a controlling spring 25,preferably a coil spring. The lower end of this spring is connected toan eye-bolt 14 connected to, and projecting upwardly from the center ofthe reticulate base 16.

The linal closure or cover 26 has an inwardly tapering lovver flange 27adapted to telescope Within the upper flanged edge of the body 10 andprovided with an outer handle 28. This cover closes in practicallyair-tight relation on the body When properly seated, and it is to avoidthe disadvantage of improper seating or failure to put the cover on,that the spring controlled closure plate 22 is provided.

It is obvious that upon proper seating of the cover on the body somepressure or ex cess of air 1s entrapped and to relieve all such excesswith the exception ot' just sufficient pressure to assist in holding theclosure plate 22 in place, the cover 26 has small air valves 29 similarfor instance to tire valves, opening outwardly and closing inwardlyunder small spring pressure.

After material, for instance rolls ot blue print paper, is placed withinthe receiving chamber, resting on the false bottom 16, by first removingthe cover 26 and lifting the closure plate 22, the latter is releasedand finds its way to properly seated position with the assistance of itsspring 25. The cover 26 is then replaced in the position shownparticularly in Figure 2, and any air finding its way into the chamberis at once dried out and sterilized by the chemicals in the lower bags20.

In case of storage, particularly for any great length of time,authorized persons will inspect and renew the chemicals it' this becomesnecessary, and it is obvious that by using proper chemicals the airthroughout the space wit-hin the body 10 will be maintained in a drystate so as to prevent deterioration of the materials placed thereinwhose preservation is desired.

. The false bottom or reticulate base 16 is normally held down with itslegs restingI on the base plate 12, by means of an` annular series of.lugs 30, connected in Vplace by bolts 32 passing through the cylinderwall and externally apertured for the reception ott seals 31. Thusunwarranted removal of the reticulate bottom 16 for removal or change ofthe chemicals can be defeated by ready detection.

1. A container of the character described having a vertical cylindricalbody provided with a closed base and a removable top closure, areticulate member within the body `dividing the 'same into an upperrelatively large storage compartmentand a lower relativelysmall chemicalholding compartment, and chemical holding means within the lowercompartment and sealed means for clamping said reticulate member inplace.

2. A container' of the character described having a closed base, areticulate bottom spaced above the base and dividing the container intointercommunicating chambers, chemical holding means in the lowerchamber, a top closure through which access may be had to the upperchamber and means working through the side of the container torclamping. said reticulate bottom to the container base.

3. A container having a top closure and closed base, a reticulate bottomtherein spaced above the base, means acting to clamp the said bottom tothe base, and a cover plate in the upperportion of the containerresiliently connected to the said reticulate bottom and shiftablevertically through the upper end of the container when said top closureis removed.

4. A container having a top closure and closed base, a reticulate bottomtherein spaced above the base, lugs within the container normallyengaging and clamping the said reticulate bottom to the base, andclamping' bolts for the lugs extending through the wall o'lE thecontainer and havingl seal receiving means.

5. A container having a removable top closure including a cover and aclosure plate seated within its upper portion below the coverand'shiftable above the container when the cover is removed, a closedbase, a reticulate bottom' spaced above the base, internal supports forsaid reticulate bottom clamping the same to said base, and a springextending vertically in the container from said reticulate bottom andconnected to and controlling the saidclosure'plate.
